Discovered growing on the sides of fallen logs in Puerto Rico, the newfound Mycena luxperpertua mushroom--which translates to "perpetual light," part of a verse in Mozart's "Requiem"--was later grown in a laboratory (as pictured above before it grew into a mushroom), an October 2009 study says.

The cultured fungus "looks like this glowing eye of some weird animal out in the forest--really neat," Desjardin, of San Francisco State University, said.
